Did a search but didn't answer questions. anyway, i want to run MT et drag slicks size 22x8x15. These will be mounted on stocksize rims. My question is, will these tires rub on anything? Will i need spacers? Which ones?

Oh, anyone know if i will need inner tubes for these tires?

Also, what is a good psi for racing? THis will be my first time using slicks. Any suggestions?...ex..lauch rpm?

Thanks in advance to anyone who responds.

I just bought the same slicks and will be running them this weekend. I was told to try running them at 12 psi. I was also told that the tube is not necessary plus it puts on extra weight. You will just have to keep an eye on the tire pressure because without tubes, air will leak out in time because the slick might slide around the wheel.

 

thanks, anyone else?

 

I ran the MT on a 15x7 Kosei, no rubbing, no tubes. Start the pressure at about 15 psi and go down from there, 12 is about the lowest that is reccommend and keep and eye on the psi. I was getting a 1.9 60ft leaving at about 5000rpm my first and only time out at the strip on slicks
